Water bag



Patented Jan. 10, 1923..

[TED STATES l, A ta-o PATENT CONNECTICUT, ASSIGNOR TO THE SEAMLESS HAVEN, CONNECTICUT, A CORPORATION OF WATER BAG.

Application filed December 19, 1921. Serial No. 523,419.

To all whom it may concern:

Be it known that I, JOHN W. PATTERSON, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in VVater Bags, of which the following is a full, clear, and exact description.

This invention relates to water bags and with regard to certain more specific features thereof to a seamless rubber bag having a constricted neck region with heat insulating means formed in homogeneous and integral fashion with the body and filler spout of the bottle.

I am aware of the fact that bottles have previously been formed with a neck insert cemented or sprung into position between the filler spout and body of the bottle and arranged and secured in position by the use of several elements which are eliminated from the bottle produced by my invention. I am also aware that round neck bottles have been previously produced in which a flange of rubber projects inwardly at the neck portion.

It is one of the objects of my invention to produce a seamless and non-leakable water bottle having certain heat insulating characteristics but without employing cements, other adhesives, wires, and flexible bands which have formerly been used. By my invention I provide a bag of great durability, overcoming the objections to former constructions which are commercially unsatisfactory on account of the hot water acting upon the cement used in the joints and destroying in a short time the liquid retaining characteristic of the bottle.

The invention accordingly consists in the various features of construction, combina tions of elements and arrangements of parts which are exemplified in the accompanying drawings and descriptive text, and the scope of the application of my invention will be indicated in the appended claim.

Referring now to the drawings, wherein is indicated one of various possible embodiments of my invention:

Fig. 1 is a view in front elevation of my improved water bottle.

Fig. 2 is a side or edge view of Fig. 1.

Fig. 3 is a fragmentary view of the bottle shown in Fig. 1 cut centrally through the upper portion of the bottle and one-half folded back to show more clearly the interior construction of the bottle at and around the neck region.

The bottle shown in the drawings is the result of an improved process of making water bottles, which is described and claimed in my co-pending application for process patent, Serial Number 523,418. The body portion of the water bag is indicated at 10. This body portion extends upwardly into a constricted neck 11 and the neck in turn extends into the flared filler spout, or funnel 12. It will be noted that the flare of the filler spout is more pronounced widthwise of the bottle than in the direction of the thickness of the bottle and it will further be noted that the dimension of the restricted neck portion is substantially greater widthwise of the bottle than in the direction of its thickness. This is in order to produce a highly desirable flat form of bottle which is exceptionally comfortable in its application to a persons body.

hen filling a bottle of this general type the neck portion is gripped by the hand and the fingers are manipulated slightly to exert pressure on the opposite flared sides of the funnel to cause it temporarily to take on a substantially round shape at the top to allow free passage for a sizable stream of fluid. My improved bottle is provided at its neck portion 11 with an inwardly extending and integral heat insulating flange 13 terminating interiorly with a threaded metal thimble 14. The rubber of the flange 13 is set, or vulcanized around the exterior threads of the thimble 14 holding it securely and permanently in position. In order to preserve the generally flat characteristic of the bottle the neck portion is of sub stantially oval shape. The flange 13, therefore, while extending in a flat-wise manner a considerable distance inward from the outer side walls of the bottle is only slightly extended inwardly from the side walls of the bottle in crosswise direction. This difference is expressed clearly in Fig. 3 of the drawings.

My improved bottle is constructed with a base 15, tab 16, the body 10, neck 11, funnel 12, and heat insulating flange 13, all homogeneous, integral and seamless. It is a wide-mouthed bottle having the characteristics of exceptional flatness and protection tical form, said neck flange providing a short to the user against burns, 0iscalding during cyhndrical opening within which a socket the filling and transporting operations. member is arranged, the flange, body and 10 \Vhatl claim 15: spout portions of sand bottle belng inte- 5 A Water bottle comprising a flat body grally molded of rubber.
